High Efficiency 2 Phase Booster LED Driver for Automotive Front Lighting NCV78902 The NCV78902 is a single−chip and high efficient two phase Booster designed for automotive front lighting applications like high beam, low beam, DRL (daytime running light), turn indicator, fog light, static cornering, etc. The NCV78902 is in particular designed for high current LEDs and with NCV78935 (triple channel Buck) or NCV78925 (dual channel Buck) provides a complete solution to drive multiple LED strings of up−to 60 V. The device integrates a current-mode voltage booster controller, realizing a unique input current filter with a limited BOM. The available output voltage can be customized.
